[0023] In this application, the technical features described in an open-ended manner include both closed technical solutions consisting of the listed features and open technical solutions that include the listed features.
[0024] Referring to Figures 1 to 6, this application specifically discloses a vehicle turning turntable trestle device, which mainly includes the following components: trestle 100, central structure 200, track structure 300, turntable structure 400, rotating structure 500, and power supply structure 600. The trestle 100 includes a central cavity 110 with an entry ramp 120 and an exit ramp 130 at its ends to guide vehicles smoothly in and out. A central structure 200 is fixedly installed inside the cavity 110. A track structure 300 surrounds the central structure 200 and is securely connected to it. A turntable structure 400 is fitted around the central structure 200, connected to it via a hinge, and is positioned above the track structure 300. A rotating structure 500 is slidably mounted on the track structure 300 and connected to the turntable structure 400; its internal components include a drive wheel set 520 and a driven wheel set 510. A power supply structure 600 is installed on the central structure 200 to provide a continuous and stable power supply to the rotating structure 500.
[0025] The vehicle turning turntable trestle device according to the embodiments of this application has at least the following beneficial effects: By supplying power to the rotating structure 500 through the power supply structure 600, the rotating structure 500 can effectively drive the turntable structure 400 to rotate smoothly around the central structure 200. When the turntable structure 400 rotates 180 degrees, vehicles located on the turntable structure 400 can turn around on the spot, significantly improving the operational flexibility and convenience of vehicle turning in scenarios such as project construction sites, thereby greatly improving overall work efficiency and reducing construction costs. In addition, the turntable structure 400 is reasonably installed on the trestle 100, which helps the rapid installation and deployment of the turntable device in this embodiment, and allows vehicles to drive accurately and smoothly onto the surface of the turntable structure 400, reducing the direct impact of vehicles on the turntable structure 400, thereby effectively extending the service life of the entire device.
[0026] In some embodiments of this application, referring to Figures 2 and 3, the central structure 200 specifically includes: a base 210, which is fixedly connected to the bridge 100 by welding or other means; a bearing 220, which is fitted outside the base 210, typically a cylindrical bearing 220 with strong load-bearing capacity to enhance stability; a bushing 230, which is covered and disposed above the base 210 and fitted outside the bushing 230, the bushing 230 being a hollow cylinder with an open bottom, the bearing 220 being installed inside the bushing 230, and the outer peripheral wall of the bearing 220 being tightly connected to the hollow inner side wall of the bushing 230 by interference fit or other means; the bushing 230 is also provided with an oil injection hole 231 corresponding to the bearing 220, one or more of which can be provided according to actual usage requirements, the main function of which is to continuously provide lubrication for the bearing 220, ensuring that the bearing 220 can operate smoothly and stably for a long time.
[0027] In some embodiments of this application, referring to Figures 2 and 3, the track structure 300 is connected to the base 210 by means of ribs 310. The ribs 310 are arranged below the bearing 220 and multiple ribs are provided. The two ends of the multiple ribs 310 are preferably fixed to the track structure 300 and the base 210 by welding, respectively. The power supply structure 600 is installed on the base 210. The power supply structure 600 adopts the anti-cable tangling power supply device with application number 2025226984354, which can maintain a stable power supply to the drive wheel group 520 of the rotating structure 500 during the continuous rotation of the turntable, while effectively avoiding the problem of cable tangling.
[0028] In some embodiments of this application, the turntable structure 400 is composed of multiple turntable units assembled together; the bushing 230 is provided with a radially protruding first connecting plate 232, while the turntable unit is provided with a corresponding second connecting plate 410, and the first connecting plate 232 and the second connecting plate 410 are reliably connected by a pin. Typically, the turntable structure 400 is composed of three or more turntable units assembled together. This modular design facilitates subsequent partial maintenance and replacement, and helps to reduce the long-term operation and maintenance costs of the equipment. The shapes of the first connecting plate 232 and the second connecting plate 410 are not specifically limited in this embodiment, but the arc shape shown in Figure 3 is preferred.
[0029] In some embodiments of this application, referring to Figures 4 and 5, the driven wheel assembly 510 specifically includes: a first top plate 511, which is connected to the turntable structure 400 by bolts or other means; a first frame 512, which is connected to the first top plate 511 by a first pin, allowing the first frame 512 to rotate flexibly around the first pin; a first roller 513, which is mounted on the first frame 512 by a second pin, and the first roller 513 can rotate around the second pin and is rolled on the surface of the track structure 300; and a first elastic member 514, whose two ends are connected to the first frame 512 and the first top plate 511 respectively, mainly used for buffering and shock absorption to prevent vehicles traveling on the turntable structure 400 from causing excessive impact on the rotating structure 500, thereby ensuring the service life of the equipment; wherein, the first elastic member 514 and the first pin are arranged at a certain interval in the horizontal direction, and the first roller 513 is installed below the first elastic member 514.
[0030] In some embodiments of this application, referring to FIG5, a first buffer member 515 is installed on the first top plate 511, and a second buffer member 516 is installed on the first frame 512. The first buffer member 515 and the second buffer member 516 are arranged opposite to each other and are both inserted inside the first elastic member 514. The first buffer member 515 and the second buffer member 516 are preferably made of elastic materials such as rubber. When the turntable structure 400 is in an unloaded state, a certain gap is maintained between the first buffer member 515 and the second buffer member 516. The first buffer member 515 and the second buffer member 516 cooperate with each other to assist the first elastic member 514 in achieving support and rebound, reduce the fatigue risk of the first elastic member 514 due to long-term stress, and further improve the overall service life of the equipment.
[0031] In some embodiments of this application, referring to FIG6, the drive wheel assembly 520 specifically includes: a second top plate 521, connected to the turntable structure 400; a second frame 522, connected to the second top plate 521 via a second pin; a second roller 523, mounted on the second frame 522 via a second pin, and the second roller 523 is rotatably mounted on the surface of the track structure 300; a second elastic member 524, with its two ends connected to the second frame 522 and the second top plate 521 respectively; and a drive member 525, mounted on the second frame 522 and connected to the second roller 523 via a transmission mechanism. The drive member 525 mainly includes a motor and a reduction gearbox, and is electrically connected to the power supply structure 600. The second elastic member 524 and the second pin are arranged at a distance along the horizontal direction, and the second roller 523 is installed below the second elastic member 524.
[0032] The main difference between the drive wheel assembly 520 and the driven wheel assembly 510 is that the second roller 523 of the drive wheel assembly 520 is connected to a drive device, which can actively provide rotational power. The remaining components are basically the same as those of the driven wheel assembly 510, thereby achieving standardization of component specifications and reducing the complexity and cost of later operation and maintenance. In the specific embodiments involved in this application, both the drive wheel assembly 520 and the driven wheel assembly 510 adopt a strategy of multiple arrangements, and the number of driven wheel assemblies 510 is significantly greater than that of drive wheel assemblies 520. Taking the turntable structure 400 with twelve rotating main beams shown in Figure 1 as an example, the drive wheel assembly 520 and the driven wheel assembly 510 are respectively installed on these twelve main beams. Typically, there are three drive wheel assemblies 520 and nine driven wheel assemblies 510. The three drive wheel assemblies 520 are evenly spaced along the circumference, and three driven wheel assemblies 510 are arranged sequentially between every two drive wheel assemblies 520, thereby forming a structural layout with uniform force and stable transmission.
[0033] In some embodiments of this application, the track structure 300 is designed to include two main parts: a fixed section and a movable section, which are connected end-to-end to form a complete circular track for supporting the turntable structure 400. The fixed section is installed inside the equipment housing cavity 110, while the movable section extends outwards into the area of the trestle 100. The two are connected in a detachable manner for easy adjustment and maintenance. Diagonal bracing is also provided between the movable section and the trestle 100 to enhance connection rigidity and overall stability. Specifically, the fixed section can be fixedly connected to the trestle 100 by welding or other methods, while the movable section maintains the same shape and size as the fixed section and is assembled using detachable connectors such as bolts. This allows the movable section to be easily removed when the turntable structure 400 needs to be disassembled and moved, effectively reducing the overall width of the equipment and improving the convenience of loading, unloading, and transportation. The addition of diagonal bracing further improves the structural stability and load-bearing capacity of the movable section in a cantilevered state.
[0034] Furthermore, in some embodiments of this application, referring to the structure in Figure 1, the overall diameter of the turntable structure 400 is larger than the width of the trestle 100, and it is circular in shape. The track structure 300 is also designed to be circular, with a diameter exceeding the width of the trestle 100. The portion of the track structure 300 that exceeds the width of the trestle 100 is the movable section, which is designed to be detachable. When the trestle 100 and the turntable structure 400 need to be disassembled and moved, the movable section can be removed, thereby significantly reducing the lateral dimensions of the equipment and facilitating transportation and on-site installation. The movable section is connected to the main body of the trestle 100 by diagonal braces. This design not only enhances the structural stability of the movable section itself but also significantly improves its load-bearing capacity and resistance to deformation.
[0035] In some other embodiments of this application, referring to FIG2, the trestle 100 is designed with an extension structure 140 extending toward the center of the receiving cavity 110. The upper surface of the turntable structure 400 is slightly lower than the upper surface of the trestle 100, and the end of the extension structure 140 is inclined to guide vehicles smoothly and steadily into the central area of the turntable structure 400, avoiding excessive load on the turntable structure 400 due to sudden height changes or concentrated force on the edges, thereby extending the service life of the equipment. Without this extension structure 140, vehicles entering the turntable from the trestle 100 are prone to generating large impacts and lateral loads on the edge of the turntable, which can easily lead to structural damage over long-term use.
[0036] Furthermore, in some embodiments of this application, the bottom of the trestle 100 is provided with a downwardly protruding load-bearing reinforcement structure, the dimension of which along the length of the trestle 100 is not less than the length of the equipment receiving cavity 110. Specifically, referring to Figure 2, this load-bearing structure 150 significantly enhances the rigidity and bending resistance of the trestle 100, effectively reduces the risk of deformation, and extends the service life of the trestle 100 under long-term heavy-load conditions.
[0037] In some specific application scenarios, such as the invert excavation area during tunnel construction, after the concrete pouring operation is completed in the tunnel after the invert excavation, the trestle device of this application embodiment can be erected. The trestle device can not only be used as a temporary bridge to effectively connect the structures on both sides and ensure the smooth passage of equipment and personnel, but also be used as a turning platform for construction vehicles, significantly reducing vehicle turnaround time, thereby greatly improving the overall construction efficiency and the smoothness of on-site operations.
[0038] In some embodiments of this application, both ends of the trestle 100 are equipped with lifting roller assemblies 160, and the upper surface of the turntable structure 400 is covered with anti-slip pressure plates. As shown in Figure 1, the lifting roller assembly 160 mainly includes traveling wheels, which can be lifted and lowered by hydraulic or electric drive. When the trestle 100 needs to be moved, the traveling wheels descend to contact the ground, realizing flexible relocation of the equipment. The anti-slip pressure plates covered on the surface of the turntable structure 400 are usually fastened to the turntable with bolts. This not only increases the contact area between the turntable surface and the vehicle tires, improving friction to prevent slippage, but also disperses pressure, reduces wear on the turntable structure, and further improves the durability and operational safety of the equipment.

Any lower limit can be combined with any upper limit to form an unspecified range; and any lower limit can be combined with other lower limits to form an unspecified range, just as any upper limit can be combined with any other upper limit to form an unspecified range.
